TFA9843J
2-channel audio amplifier (SE: 1 W to 20 W or BTL: 4 W to
40 W)
Rev. 02 — 19 January 2004
Preliminary data
1.
General description
The TFA9843J contains two identical audio power amplifiers. The TFA9843J can be
used as two Single-Ended (SE) channels with a fixed gain of 26 dB or one
Bridge-Tied Load (BTL) channel with a fixed gain of 32 dB.
The TFA9843J comes in a 9-pin DIL-bent-SIL (DBS7P) power package. The
TFA9843J is pin compatible with the TFA9842J and TFA9841J.
The TFA9843J contains a unique protection circuit that is solely based on multiple
temperature measurements inside the chip. This gives maximum output power for all
supply voltages and load conditions with no unnecessary audio holes. Almost any
supply voltage and load impedance combination can be made as long as thermal
boundary conditions (number of channels used, external heatsink and ambient
temperature) allow it.
